(4eiv)
(iv)2k(s) + 2H2O —-> 2KOH(aq) + H2(q)


You Are Good To Go.

(5ai)
Standard electrode potential is the potential difference between an element and a solution of its ions under standard condition

(5aii)
I. Oxidation takes place at hydrogen electrode

H2(q) —–> 2H^+(aq) + 2e^-

II. Reduction takes place at copper electrode
CU²+(aq) + 2e ——> CU(s)

Overall reaction
CU(s) + 2H^+

TABULATE
-COMPOUND (Fes)-
(i) It can not be separated by physical means
(ii) The composition is fixed
(iii) Homogeneous
(iv) Can be represented by a chemical formula

-MIXTURE of Fe and s-
(i) It can be separated by physical means
(ii) The composition of a mixture can vary
(iii) Homogeneous or Heterogeneous
(iv) Can not be represented by a chemical formula

(5bii)
6P , 13Q and 15R
P=C
Q=Al
R=P
(I) Q is metal
(II) R is a non-metal
(IIII)Q and R belong to the same period .

(5ci)
V1= 300cm^3
P1= 410mmHg
P2=?
V2= 130cm^3
P1V1=P2V2
P2= P1V1/V2
P2 = 410*300/130=946.2
P2 = 946.2mmHg

(5cii)
2CuO(s) + C(s) —-> 2CuO(s) + CO2(g)

H2O(g) + C(s) —-> CO(g) + H2(g)

(5ciii)
(I) 20L and 17B
L= calcium
B= chlorine
(II) Calcium chloride
(III) Electrovalent combination
(IV) It is used in desiccators as drying agent for all gases except ammonia
